The other concept that might be of benefit is a "dead" jail vs. a "live" jail 
-- with TCP connections taking a while to run down, there can often be 
dangling jail references that don't garbage collect for a few minutes. 
Perhaps, where there is ambiguity, live jails (ones with referencing 
processes) should be preferred to dead ones.
